Duck Hunters... Explain to me why.....

Every Saturday and Sunday morning, I hear a MILLIONs of shots go off. I mean, I'm not a hunter, so I don't know the ins and outs, but, aren't ducks hunted with a shot gun? Meaning a double barrel, meaning 2 shots?

When I hear them, there are more then 2 shots. Is this like 6 guys hunting together, are these ducks really that elusive? Last Saturday there was a string of at least 12 - 15 shots in a row. I'm all for sporting hobbies, but I'll tell you I'm looking forward to the 15th when the dogs no longer jump into my bed to seek refuge from the gun shots!
